Trevor Gamblin 1f3753bb0f qemuarm: check serial consoles vs /proc/consoles
Note that this patch affects qemuarm AND qemuarm64.

When booting a VM and during operation, the following message
periodically appears:

INIT: Id "hvc0" respawning too fast: disabled for 5 minutes

This is because hvc0 is specified in SERIAL_CONSOLES in qemuarm.conf
and qemuarm64.conf, but it is not in /proc/consoles and
SERIAL_CONSOLES_CHECK is not specified, leaving getty to attempt to
enable hvc0. Add SERIAL_CONSOLES_CHECK to both conf files so that
hvc0 isn't enabled if it hasn't been set there or in local.conf.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
